Abstract
Purpose
The purpose of this paper is to propose a framework for the standardisation of the work breakdown structure (WBS) for building projects. This is based on the premise that buildings in general retain basic elemental options, and that there is a commonality of activities in the procurement of building projects.
Design/methodology/approach
To achieve the objective, the general practice of developing the WBS is investigated. This is achieved by means of an industry‐wide questionnaire survey designed to identify the most widely used criteria among UK construction organisations in segregating building works into packages. The survey also investigates the sequencing of these criteria across the WBS hierarchy.
Findings
The findings reveal that the most frequently used decomposition criteria in the formulation of WBS for building projects are elements, work sections, physical location and construction aids. The proposed framework is presented as a hierarchical decomposition of a building project based on these criteria. It allows for flexibility in level of detail while maintaining a rigid sequencing of the criteria based on their frequency of use.
Originality/value
This paper reports on a specific part of an EPSRC funded project that aims to investigate the application of computer vision techniques to the on‐site measurement of construction progress. The part reported in this paper addresses planning issues that will lead to automatic generation of work packages. Previous studies have focused on automating the planning aspect by associating individual components with schedule information. However, large construction projects usually consist of thousands of components. Planning and tracking progress at the level of the component is unrealistic in these instances. The standardisation framework reported in this paper will form the basis for automating the formulation of work packages, thus providing a uniform basis for tracking progress (based on computer vision) during project execution.

Abstract
Purpose
Asset inventory is an essential part of any building asset management system and is needed by such functions as condition assessment and deterioration prediction. Previous studies in asset management systems have suggested the use of one of the many standard construction classification systems, such as UniFormat or MasterFormat, in achieving the goals of asset management. However, each classification system has its unique features, and it has been developed for different purposes and may not necessarily be directly adaptable to asset management. A proper classification system is thus needed to achieve the goals of building asset management effectively. Such a system must take into consideration the objectives and functions of asset management. Therefore, the purpose of this paper is to establish a unified work breakdown structure (WBS)-based framework for building asset inventory.
Design/methodology/approach
The WBS-based framework aims to cover the entire lifecycle of an asset so as to provide the unified classification system for asset inventory. The proposed framework is developed based on appropriate building standards. Also, comprehensive levels of details are included for space functions and locations for all assets in any type of building. Furthermore, this framework takes into consideration utilities in any kind of building project. As such, the WBS-based framework proposed in this research endeavor provides the basis for effective asset management. An educational building case study is presented and discussed to demonstrate the effectiveness of the proposed framework for asset management.
Findings
The unified WBS-based framework for building asset management effectively classifies asset inventories and facilitates decision-making in asset management during the lifecycle of an asset.
Originality/value
This research synthesizes a unified WBS-based framework for building asset management, which allows for a more effective lifecycle building asset management.

Abstract
Purpose
The purpose of this paper is to identify and map out various aspects and key elements, which are necessary to strengthen an effective and systematic whistleblowing system (WBS) and ensure adequate protection in accordance with the characteristics typical of Indonesia.
Design/methodology/approach
This research emphasizes the extensive use of literature review and previous research that analyze whistleblowing as an issue and ethical challenge in public institutions. This research also reviews documents pertaining to the formulation and implementation of existing WBS. Additionally, this research also analyzes some cases experienced by a number of whistleblower figures in Indonesia as a contribution and recommendation to parties interested in formulating a more effective and systematic WBS.
Findings
An effective and systematic WBS, assuring adequate protection, needs a number of key elements which will be identified and mapped out in this research and, subsequently, categorized into several aspects covering human and ethical culture; policy; legal protection; organizational structure; and procedures and process in accordance to Indonesia’s specific characteristics.
Practical implications
The paper can be a source to explore anti-corruption policy and the prevention approach of corruption based on Indonesian perspectives.
Originality/value
This paper is a significant undertaking aimed at raising public trust in public institutions and providing adequate protection to whistleblowers. It also contributes by encouraging the public organization to prevent corruption and other wrongdoing, which, nowadays, are common in Indonesia.

Abstract
Purpose
Interventions that promote both mental and physical wellbeing have been advocated for people with mental health difficulties, as they have been found to engage less in healthy behaviours and have lower levels of physical fitness. However, no optimal approach to facilitate this undertaking has been identified. The purpose of this paper is to explore the experiences of people with psychological distress who accessed a social enterprise that fosters the building of positive social networks in the community, as part of a personalised recovery programme. The intention was to gain an insight into its therapeutic effect in relation to mental and physical health.
Design/methodology/approach
An exploratory survey design was undertaken with a purposive sample of 50 individuals who had attended the enterprise. Descriptive statistics and thematic analysis were employed to analyse the data from both closed and open-ended questions.
Findings
The wellbeing service appeared to provide a supportive environment that offered people access to social networks through their participation in local services and activities. Fostering participants’ active participation, connection building and the ability to make meaningful contributions helped to facilitate health behaviours that had a positive impact on their health and wellbeing.
Originality/value
This study highlights the potential role of a social enterprise in optimising the social context for promoting the health and wellbeing of people with mental health difficulties.

Abstract
Purpose
The purpose of this paper is to summarise a successfully defended doctoral thesis. The main purpose of this paper is to provide a summary of the scope, and main issues raised in the thesis so that readers undertaking studies in the same or connected areas may be aware of current contributions to the topic. The secondary aims are to frame the completed thesis in the context of doctoral‐level research in project management as well as offer ideas for further investigation which would serve to extend scientific knowledge on the topic.
Design/methodology/approach
Research reported in this paper is based on a quantitative study using inferential statistics aimed at better understanding the actual and potential usage of earned value management (EVM) as applied to external projects under contract. Theories uncovered during the literature review were hypothesized and tested using experiential data collected from 145 EVM practitioners with direct experience on one or more external projects under contract that applied the methodology.
Findings
The results of this research suggest that EVM is an effective project management methodology. The principles of EVM were shown to be significant positive predictors of project success on contracted efforts and to be a relatively greater positive predictor of project success when using fixed‐price versus cost‐plus (CP) type contracts. Moreover, EVM's work‐breakdown structure (WBS) utility was shown to positively contribute to the formation of project contracts. The contribution was not significantly different between fixed‐price and CP contracted projects, with exceptions in the areas of schedule planning and payment planning. EVM's “S” curve benefited the administration of project contracts. The contribution of the S‐curve was not significantly different between fixed‐price and CP contracted projects. Furthermore, EVM metrics were shown to also be important contributors to the administration of project contracts. The relative contribution of EVM metrics to projects under fixed‐price versus CP contracts was not significantly different, with one exception in the area of evaluating and processing payment requests.
Practical implications
These results have important implications for project practitioners, EVM advocates, as well as corporate and governmental policy makers. EVM should be considered for all projects – not only for its positive contribution to project contract development and administration, for its contribution to project success as well, regardless of contract type. Contract type should not be the sole determining factor in the decision whether or not to use EVM. More particularly, the more fixed the contracted project cost, the more the principles of EVM explain the success of the project. The use of EVM mechanics should also be used in all projects regardless of contract type. Payment planning using a WBS should be emphasized in fixed‐price contracts using EVM in order to help mitigate performance risk. Schedule planning using a WBS should be emphasized in CP contracts using EVM in order to help mitigate financial risk. Similarly, EVM metrics should be emphasized in fixed‐price contracts in evaluating and processing payment requests.
Originality/value
This paper provides a summary of cutting‐edge research work and a link to the published thesis that researchers can use to help them understand how the research methodology was applied as well as how it can be extended.

Abstract
Purpose
The study aims to explore the novel issue of how consumers perceive sponsorship initiatives by foreign companies and how the sponsors' country-of-origin (COO) cue may influence sponsorship outcomes.
Design/methodology/approach
The measurement model and proposed relationships were tested based on a sample of 811 Chinese consumers using confirmatory factor analysis and structural path analysis.
Findings
The results reveal that attitudes toward the sponsor completely mediate the effect of event involvement on willingness to buy from the sponsor (WBS). Attitudes toward the sponsor also partially mediate the relationship between economic animosity towards a specific sponsor's COO and WBS. Additionally, the level of a country's economic competitiveness found to moderate the negative relationship between economic animosity, attitudes toward the sponsor and WBS.
Research limitations/implications
The nature of the product type and the desire of the consumer to own such a product may have influenced the measurement of willingness to buy.
Practical implications
The research adds to the existing knowledge by identifying the opportunities and potential biases that a foreign company may encounter when considering sponsoring a mega sport event in a different cultural context. The study helps managers to understand how sports sponsorship could be used effectively in emerging markets.
Originality/value
The proposed conceptual model advances the application of classical conditioning theory, the consumer animosity model of foreign product purchase and the belief-attitude-intention hierarchy in the sponsorship arena. It is the first investigation of the role of event involvement and economic animosity in understanding sponsorship responses.

Abstract
Compiling bid proposals for construction projects is a process that depends on extensive computation as well as on experience‐based judgement. Despite the proliferation of estimating tools, bid proposals focus primarily on the computational component and leave the more difficult aspects of risk assessment and mark‐up estimation to estimators' judgement. This may lead to unrealistic estimates that do not account for the operational environment of projects. Such estimates often result in either losing bids or inflicting undesirable cost overruns. In an effort to circumvent such drawbacks, this paper presents a structured system for cost estimation and bid preparation. Unlike current tools, the proposed system supports a holistic bid‐preparation process, accounting for a number of quantitative as well as qualitative factors that are used in practice for bid preparation. The system incorporates three principal features: 1 Integrated cost and schedule computation 2 Adequate risk assessment and mark‐up estimation 3 Optimum bid unbalancing and cash flow optimization. The developments made in the integrated system are described along with a PC‐based prototype Estimator, developed to automate the process. An example application is presented to illustrate the capabilities and essential features of the prototype and demonstrate its practicality.
